Abstract:
This report details the development of detonation spray models at the U.S. Naval Research Laboratory NRL. Previous work on sprays using particle tracking methods are adapted to the current CFD codes, specifically the DASLIB programs and the JENRE program, which has recently been extended for reacting flow fields. Initial results compare a series of shock tube simulations seeded with glass particle and water droplets to earlier work. Results show that the new DASLIB programs match previous results almost exactly, while the JENRE program also compares very well. The current simulations extend the previous work by showing more highly resolved two-dimensional results and improved thermodynamics. The report also considers a detonation tube with JP-10 droplets and gaseous oxygen. The gas-phase stoichiometric JP-10oxygen detonation matches the calculated C-J detonation velocity of 2300 ms, while the liquid JP-10oxygen detonation with 10 mm droplets results in a detonation velocity of 2170 ms. Two-dimensional liquid JP-10oxygen simulations showed the formation of detonation cells and unique features not found in gaseous detonations.
